Background

Side branch occlusion is one of serious complication that may occurs during bifurcation percutaneous coronary intervention (PCI). Several prediction models of side branch occlusion that involving left main and non-left main bifurcation has been established, but some results remained debatable. This study aimed to specifically identify the predictor of side branch occlusion in the non-left main bifurcation PCI (stenting).

Methods

A case control study was conducted in patients underwent non-left main bifurcation intervention using provisional stenting with visual estimated side branch diameter ≥ 1.5 mm, in Dr. Kariadi General Hospital from April 2021 to March 2022. Side branch occlusion was defined as any decrease in TIMI (Thrombolysis in Myocardial Infarction) flow grade after main vessel stenting. Variables were analyzed with the RadiAnt DICOM software.

Results

A total of 212 lesions in 198 patients were fulfilled the criteria. Side branch occlusion occurred in 40 lesions (18.8 %). The cut off value of side branch occlusion for carina bifurcation angle and bifurcation angle were 29.9° and 54.7°, respectively. Multivariate analysis showed that independent predictors of side branch occlusion were ipsilateral plaque distribution of the proximal segment main vessel (OR 3.34; 95% CI 1.10 - 10.09; p = 0.032), stenosis of the bifurcation core ≥ 70% (OR 4.16; 95% CI 1.11 - 15.65; p = 0.035), carina bifurcation angle ≤ 29.9° (OR 5.45; 95% CI 1.65 - 17.96; p = 0.005), and bifurcation angle ≤ 54.7° (OR 3.70; 95% CI 1.15 - 11.90; p = 0.028).

Conclusion

In the non-left main bifurcation PCI, independent predictors of side branch occlusion were ipsilateral plaque distribution of proximal segment main vessel, stenosis of the bifurcation core ≥ 70%, carina bifurcation angle ≤ 29.9°, and bifurcation angle ≤ 54.7°.
